Thanks LCR and Possum, I would love to have seen that Hummer on Lippencott. It really comes down to knowing your vehicle, doesn't it? We went down Sperry Wash on the way home (furnace creek rd to dumont dunes). It was a kick in the head (more challenging than lippencott). We were the biggest vehicle on the trail (Jeep Grand C.). Lots of quads and cycles. A few Wranglers. I would love to play with a Hummer there. Happy New Year,Ron
